Detailed description of the invention
By further illustrate technological means that the present invention taked by reaching predetermined goal of the invention and
Effect, below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment party according to the present patent application
Formula, step, technical characteristic and function thereof, effect, after describing in detail such as.
In one seed melon, the extracting method of Cit, comprises the steps:
1) ultrafiltrate is prepared: the seed melon melon pulp after removing seed is squeezed the juice, is centrifuged, is taken supernatant, will
Ultrafiltration after supernatant micro-filtrate membrane filtration, then concentrate, obtain ultrafiltrate, ultrafiltrate is concentrated;
2) upper prop wash-out: by ultrafiltrate pH value to 1.0-2.0, obtain upper prop liquid, upper prop liquid is led to
Enter cationic ion-exchange resin exchange adsorption citrulling, when in detection efflux, Cit quality is dense
Degree is with when in ultrafiltrate, Cit mass concentration is identical, and exchange adsorption is complete, then uses ammoniacal liquor
As eluant, eluent, eluting, wash-out terminal is eluate ninhydrin reaction for feminine gender, collects
Eluent;
3) decompression distillation: obtain inspissated juice after the distillation and concentration that reduced pressure by eluent;
4) crystallization: inspissated juice absolute ethyl alcohol is crystallized, repeats crystallization 2-3 time, freeze-drying
After Cit crystal.
The present invention regulates pH value after being concentrated by ultrafiltrate, obtains upper prop liquid, by micro-filtration and ultrafiltration
Remove in upper prop liquid the impurity such as various albumen, carbohydrate, improve the adsorbance of resin after upper prop, subtract
The light pollution to resin, extends resin and uses the cycle, improve product purity.
In the present invention, the pH value of upper prop liquid has two aspects to the impact of ion-exchange effect, on the one hand
It is the impact that resins exchange group is dissociated, is on the other hand to affect dissociating of adsorbed material;
So the pH value of upper prop liquid mainly affects dissociating of Cit;Take upper prop liquid 30mL respectively,
Concentration is the former extract of 0.9569mg/mL, adjusts different pH value with acidometer, adds 3g
Wet resin, shaking table Static Adsorption 4h, rotating speed is that 114r/min investigates different pH value to tree
The impact of fat static adsorbance, as it is shown in figure 1, adsorbance difference is little when pH is 1-2,
And adsorbance is maximum under this pH value, therefore to reach preferable adsorption effect, the present invention will
The pH value of upper prop liquid is adjusted to 1-2;Because the isoelectric point of Cit is 5.97, pH is 1-2
Just away from the isoelectric point of Cit, so basic positively charged, adsorbance is optimum, if extracting
Liquid pH is just in the range of 1-2, then extract need not regulate pH and gets final product direct upper prop.
In order to make citrulling have more preferable adsorbance in the present invention, cationic ion-exchange resin needs
Pretreatment, will be placed in plastic containers by resin, rinses with clear water, and be soaked in water resin 12-24
H so that it is fully expand, then loads in post by resin, with the HCl of the 4% of resin volume 5 times
Flow through resin bed with the speed of 1mL/min, repeatedly rinse 3 to 5 times;Use low pure water the most again
Washing resin from top to bottom, until efflux pH is about 4;Again with resin volume 3 times 4%
NaOH solution processes, and is then washed to alkalescence, then the HCl of 4% with 3 times of resin volumes
Solution processes, and is then washed to pH and is about 4, without Cl-?.
Preferably, described microfiltration membranes is the Flat Membrane in 0.1-0.3um aperture, and ultrafiltration is chosen and retained point
Son amount is the daltonian Flat Membrane of 5000-7000, and the ultrafiltration time is 20-80min;Described ultrafiltration
After liquid concentrates, Cit mass concentration is 0.2-4.0mg/mL.
It is more uniform that microfiltration membranes used in the present invention has aperture ratio, and porosity is high, takes off without medium
The features such as falling, quality is thin, and resistance is little, and filtering velocity is fast, the Flat Membrane using 0.1-0.3um aperture can
To be filtered to remove solid insoluble matter and most big molecule class impurity, use 5000-7000 afterwards
After daltonian flat membrane ultrafiltration, other materials such as microorganism, colloid can be removed.
In order to clearly go up the column liquid concentration impact on resin adsorption performance, compound concentration of the present invention divides
Be not 0.2392,04785,0.9569,1.1438,1.1798,1.8594,2.3359mg/mL
The each 30mL of Cit sample liquid, add 3g wet resin, shaking table Static Adsorption 4h,
Investigate the variable concentrations impact on resin static adsorbance, as in figure 2 it is shown, along with Cit
The increase of concentration, adsorbance increases accordingly, and this result matches with adsorption equilibrium theory, will be super
The suitable concentration of filtrate can improve concentration, reduces the volume that pregnant solution is collected, beneficially resource reclaim,
Save the consumption of the energy.Therefore, the present invention selects through the ultrafiltrate concentrated as upper prop liquor ratio
Advantageous.
Preferably, described cationic ion-exchange resin is 001 × 7 type, HD-8 type or 732 types, institute
The column flow rate of crossing stating upper prop liquid is 3.6-7.2BV/h.
In order to clearly cross the column flow rate impact on Cit exchange capacity, the present invention respectively takes 25mL
The cationic ion-exchange resin dress post pre-processed, with Cit concentration as 3.9685mg/mL
Post exchange crossed by extract, controlled post speed and is respectively 3.6BV/h, 5.4BV/h, 7.2BV/h,
In units of every 10mL, collected post liquid respectively, measure and wherein cross Cit concentration in post liquid,
Till in efflux, Cit concentration is 3.9685mg/mL, as it is shown on figure 3, along with
Crossing post flow velocity to increase, upper prop liquid used is long-pending to be reduced, cationic ion-exchange resin exchange L-melon ammonia
The amount of acid reduces.When flow velocity is 3.6BV/h, the exchange capacity of resin is 31.75mg/mL;
When flow velocity brings up to 7.2BV/h, its exchange capacity drops to 20.64mg/mL.Obviously, this
Relevant with Cit diffusion velocity in resin.Cationic ion-exchange resin and Cit
Exchange rate determines that, and Cit is continuous between solution and resin during crossing post
Being diffused, when column flow rate is less excessively, Cit can carry out sufficient ion friendship with resin
Changing, therefore, its exchange capacity is big;Increasing along with crossing column flow rate, Cit flows through exchange column
Time gradually decreases.If in extract, Cit concentration is higher, then part Cit comes
Carrying out ion-exchange reactions just by exchange column not as good as with resin, therefore, resin is to Cit
Exchange capacity reduce.
Preferably, the molar concentration of described ammoniacal liquor is 0.6-0.9mol/L, and elution flow rate is 3.6-7.2
BV/h。
The isoelectric point of Cit is 5.97, pH=1-2 just away from the isoelectric point of Cit,
Now Cit is attracted in resin with cationic form.The present invention selects ammoniacal liquor to be wash-out
Agent is because the aobvious alkalescence of ammoniacal liquor, creates alkaline environment, and now solution environmental pH is more than Cit
Isoelectric point, can be eluted out Cit from resin.Because amino acid is in alkalescence condition
Change of configuration is the most easily caused to lose physiologically active, so eluent can use decompression distillation
Mode removes eluant, eluent.Ammoniacal liquor is volatile, uses distillation under vacuum to be easy to remove ammonia after wash-out
Water, therefore select ammoniacal liquor as eluant, eluent.
The effect of wash-out can be directly affected as eluant, eluent, the concentration of eluant, eluent using ammoniacal liquor, as
Really eluant strength is higher, and eluting power is the strongest, and the impurity flow down from resin is the most a lot,
If eluant strength is the dilutest, then the volume collecting liquid will strengthen, and goes out peak smooth, during collection
Between can extend.The present invention take 10mLL-citrulling solution that loading concentration is 0.3968mol/L,
Amount of resin is the 732 type cationic ion-exchange resins dress posts of 20mL, with the ammoniacal liquor of variable concentrations (0.2,
0.6,1.0mol/L) it is eluant, eluent, control elution flow rate is 7.2BV/h, with every 10mL is
Unit collected post liquid respectively, measures the absorbance of efflux, is converted into Cit content.
With eluant, eluent volume as abscissa, stripping post liquid Cit content is that ordinate draws wash-out
Curve, compares the impact on wash-out effect of three different eluant strengths.As shown in Figure 4,1.0
Mol/L wash-out power is the strongest, and acquisition time is short, but the most in view of its outflow impurity, so this
The ammonia spirit of bright preferred 0.6mol/L, although collect the big of the long-pending relatively 1.0mol/L of liquid,
But it goes out peak unevenness.
The present invention also provides for the preparation method of Cit effervescent tablet in a seed melon, and the method is first
